cnenmmssxorrr, or mi. VALLEY, camronm f msm-ennuie MACHINE.

To all wom it may concern:

Be it known that I, CAnL'RAHssKorFF, a citizen ofthe United States, residing at Mill Valley, in the county of Marin, State of California, have invented a new and useful Paper-Curing Machine, of which the following is a\ specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a paper curing machine adapted to treat forty to sixty thousand sheets of paper at one time.

It will be understood by those skilled in the art that printing establishments must cure the paper used by them sothat it will take the ink, the curing taking place in air of substantially the same hygrometric condition and temperature as the press room. Under ordinary conditions this necessitates hanging the paper up so that the air can come in contact with each sheet thereof for a sufficiently long time to bring the paper to the condition requisite for proper printing, and this necessitates 4keepin outof' use a great quantity of paper, while at the same time 1t occupies a -large amount of space in establishments where considerable prlnting is done.

With the present invention the time ofcuring the paper is greatly reduced because a proper circulation of air is kept up throughout the bunches of paper hung up thereby insuring a proper treatment of each sheet in the minimum time.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but am aware that there may be many modifications thereof.

Figure 1 is a side elevation of the complete apparatus showing the several fans used to treat the paper,

Fig. 2 is a. plan vlew of the complete apparatus,

Fig. 3 is a cross sectional view of the apparatus on the line 3 3, Fig. .1, and

Fig. 4 is a plan view of one form of reduction gear used, for moving the fans along the paper rack.

rlhe numeral 1 indicates the Hoor of the press room, 2 and 3 supports extending upwardly therefrom and 4 the ceiling. Secured to the ceiling are a pair of 'oists 5 and 6, which joists support hangers and 8 carrying stringers 9 and 10. The stringere 9 and 10 are provided with brackets 11 and Specification o1 Letters Patent.

'may be moved longitudinally ofvsaid rods purpose of accommodating different for the lengths of paper and each Stringer has a plurality of depending lugs 16, each lug having a finger 17 pivoted thereto, which nger is so shaped that it will bind a bunch of sheets against the next adjacent lug when the weight of-.the bunch of sheets and the weight of the finger 1-7 bears thereon.

Depending from the ceiling are a plurality of brackets 19, 20, 21, 22, 22 and 23. The brackets 19 and 23 support pulleys 24 and 25 respectively, while the brackets 20, 21, `22 and 22 support a -rail 26. A Wire cable 27 passes over the pulleys 24 and 25 and it is connected with the fan frames 28, 29 and 30. The fan frame 28 consists 'of two vertical bars 31 and 32 connected with Patented Apr., 24, 1917.' Application mea april 24, 191e. serial no. 93,215.

diagonal braces 35 and 36, the upper end of said bars being hooked over to form two bearings for the trunnion of the two wheels 37 and 38. The lower end of the bars 31 and 32 have a plurality of openings thereinto receive the bolts 39 and 40 which support the fan motors 41 to adjust the fans to the center of the sheets. Thefans are of the well known portable type and have the usual controlling mechanism in the base 42, wire guards 43 and fans 44.

Mounted on the post 2 is a bearing 45 for a sprocket wheel 46, a sprocket chain 47 passing over said sprocket wheel and over another sprocket wheel 48, the latter sprocket wheel being supported in a bearing 49 and having a worm wheel 50 on the shaft-51. rlhe sprocket chain carries a bolt 452 to which is pivoted a link 53, said link being also pivoted to one of the bars 32 of fan frame back and forth at the same rate the chain 47' moves. idlers 47 as its length demands.

The frame 54 has upright members 55 and 56 which are suitably secured to the ceiling The chain has such ico 4, and they have bearings 57 and 58 for the shaft 59 which carries the worm 60. The

shaft 59 carries a large pulley L,61 under' which the belt 62 passesv from the pulley 63 on the shaft of the motor M, said motor beto suit' the .size paper mg mounted on a shelf 64 connected with the depending hangers 55 and 56.

At a distance from the fan 41 corresponding to the distance the fan 41 moves, that is the length between the two sprocket wheels 46 and 48 there is a 'second fan ,66 mounted in the frame 29, which frame has a hook 67 and supporting wheel 68 bearing on the rail `26. rlhe fan 66' is substantially-the same as the fan 41 and may be adjusted in position in the frame 29 being treated. At a distance from the fan 66 the same as the travel ofthe fan 41 there is another fan 70. This fan is mounted in the frame 30, which frame has a hook 71 at its upper end to form bearin s for the wheel 72 riding on the rail 26, an if desired and the number of sheets requiresit, other fans may be used at will.

' The fans receive power from a`iexible cable 7 3, which extends to the fan base '42 and thence by way of the cable 74 to the motor Vof the fan 41. Another cable 75 extends from this fan up over the cable 27 from which point it extends to the base 7 6 of the fan 66. A cable 77 supplies .current to the fan motor 66 while a ca le 78 extends up and is connected with the cable 27, from thence it'extends to the base 79 of the fan 70. A trou h 8,0 is positioned below the fans artly or the purpose of receiving the cable 3 and partly to prevent the workmen from accidentally coming into contact with the fans.

lnasmuch as the cable 27 i's connected to the frames 28, 29 and 30 and to the cables 75 and 78, said cable 27 will be caused to travel back and forth at the same rate as the frame 28 travels ,under the force applied to it by the chain 47.

It is arranged foreach worm wheel 50'y and sprocket wheel 48 to travel about one revolution per minute so that the movement of the fans up and down the long row of suspended sheets of paper is very slow. The

result of this is that the air from the fans is vblown into the edge of successive bunches of paper and spreads them al1 apart uniformly,-

and owingto the adhesion of the air the paper sheets donot come together for a long time, so thatwhen bunched they will stay open until the fans return again and again blows the press room air between the bunches Iof sheets of paper.

v While one method of driving the sprocket chain 47 has been shown in Figs. 1 and 2,

it will be apparent that other'methods may be used to roduce the extremely slow mo-v tion desire that is about one turn of the sprocket wheels driving saidl chains, and such a driving mechanism is shown inFig. 4. In this figure the base upon which the motor 91 is mounted, said motor having a small gear 92 which engages a large gear 93. The ,large gear is the numeral 90 indicates 1 naeaeia loosely mounted on a fixed shaft 94 supported in a bracket 95 and it/carries a small each revolution of the pinion 96 around the fixed gear, thereby givlng a great reduction in speed to the sprocket wheel 99. v

ln operation bunches of sheets about 150 to 200 sheets are hung up as indicated at S. The fans and motor M are started whereupon the travel of the chain 47 will cause the series of fans to move slowly across the ends of the sheets, the air from the fans being blown into the bundles of paper and spreading the sheets apart. 'lhe adhesion of air to the sheets of paper is sucient to hold the sheets apart for a considerable time'and the fans travel up and down the bundles blowing the air inte them, and the desired missible modifications;

1. A paper curing machine comprising a rack adapted to support a series of paper bundles from the upper edges thereof, a fan adapted to blow a1r into the edges of the paper bundles, and means to cause said fan to travel back and forthacross the edges of the paper bundles.

2. A paper curing machine comprising a rack adapted to support a plurality of paper bundles by the upper edges of the paper sheets, afan adapted to blow air into the edges of the paper bundles, means whereby the position of the fans may be adjusted with respect to the paper bundles, and means to slowly move the fan back and forth across the edges of the paper bundles.

3. A paper curing machine comprising a frame adapted u to support a. plurality of bundles of paper sheets by the upper edges thereof, a plurality of fans adapted to blow air into the edges of the paper bundles, a.

suitable connection between the several fans, and means to move the fans back and forth across the edges of the pa er bundles.

4. A paper curing mac ine comprising a rack adapted to suspend a plurality of bundles of paper sheets from'the upper edges of the sheets, a the edges of the paper bundles, a. wheeled frame in which said fan is supported, a track on which said frame rides, a sprocket fan adapted to blow air mto chain extending alongthe track, alink conknecting the wheeled frame and sprocket frame adapted to support a plurality of bun-4 dles of paper sheets by the upperedges of said sheets, a plurality of wheeled frames, a track on which they ride, a fan supported in each frame, a sprocket chain extending along the track, a link connected with one of said frames and with the sprocket chain, means to drive said sprocket chain to cause the Wheeled frame to travel back and forthv across the ends of the paper sheets, a pair of pulleys, a cable over which said pulleys pass, and connections between'saidfcable andthe other fan frames whereby all of the fans will be caused to travel back and forth across the ends of the paper sheets.

6. A paper curing machine comprising a frame adapted to support a, plurality ot bundles of paper sheets by the upper edges of the sheets, a wheeled frame, a track on which said wheeled frame is mounted, a fan adjustably supported in said wheeled frame, a sprocket chain, a link connecting said sprocket chain and frame for causing the fan to move back and forth across the ends of the paper sheets, a motor, and a suitable reduction gear between the sprocket chain and the motor whereby the sprocket chain will be driven very slowly. l

4 In testimony whereof I have .hereunto set my hand this 15 yday of April A. D. v1916.
